Idle Problem.

[SupraHuman]

I have a J-spec Supra mk.4 NA-T with a MAP-ECU.I am running a 850CC fuel map,but got 650CC injectors fitted.The idle on my car has always been alright although the mix was very rich.After leaning out the map and to 12.5 AFR at idle,the car will not idle when put into drive.The Idle,or lack of it is from 900RPM to 200 RPM and later it just stalls.It only happens when auto box is in D,1,2,3 or R.(under load)
Timing?(Retard)
TPS issues??
Any ideas folks??
Thanx.

post up your map, i'm no expert, but can take a look it for you (map-ecu user too).
